Radhakrishnan said that Sampath Lakmal de Silva had information about killing done by the army.^[3]

The International Federation of Journalists condemned the murder:

"The IFJ supports its affiliates in Sri Lanka in condemning the murder of de Silva, and in calling upon authorities to investigate the case immediately so that those responsible can be brought to justice as soon as possible. Sri Lankan authorities must take more responsibility for these attacks and establish stronger protections for media workers to prevent journalists like de Silva senselessly losing their lives just for doing their jobs."^[5]
